Re: BackroadCR-V's High Mileage B18C1 + Boost Progress Build Thread
Help me out here. Today for the 1st time I'm seeing timing spikes both up and down.
ive noticed these before when the car does a cold start. It only happened while the car was cold. I can here it happening it's very sudden, like a single stutter. But until today it has never happen while driving. It's not doing it all the time, just very randomly and this is the 1st time I've seen it happen on a WOT run.
I checked all my ignition connections and they all seem tight. ANY ideas about what this could be? Here is a 4th gear pull that it happened on.
Not good. I'm gonna take it easy until I get this fixed. Dont like that big 42' spike at all.
Any Ideas?

Re: BackroadCR-V's High Mileage B18C1 + Boost Progress Build Thread
So it appears the spikes maybe related to the flex fuel setup. When I turn flex fuel off the spikes stop.
i got a decent soldering iron and although my soldering skills suck, I soldered the resistor.
It did not fix my ignition spike problem though. So at this point I'm going to make a e60 map so I can drive the car and double check that the ignition spikes are gone with flex fuel disabled. And I'm going to go through the entire harnes AGAIN and redo it. I'll either get higher quality quick disconnects or hardwire everything. Then HOPEFULLY this issue is gone cause I really want my flex fuel setup to work

Just a quick tip to improve your soldering skills. Don't heat the solder and let it run onto the wire, instead heat the wire while holding the solder against the wire, when it's hot enough the wire will wick the solder in and you will have a really good connection. From the pic that looks like a "cold solder joint" witch is not good. Hope that makes sense and helps man.
Re: BackroadCR-V's High Mileage B18C1 + Boost Progress Build Thread
Your bulky soldering on the resistor changed the resistance of the resistor there is no need for all the excess wrapping of wire...like stated above a its a very cold and incomplete solder
Re: BackroadCR-V's High Mileage B18C1 + Boost Progress Build Thread
On a good note I tuned my car with a e50 mix yesterday.
Even with the flex fuel I was hoping somewhere between e40-e60 would give me enough to run full timing.
I'm mixed to e50 right now and the car is running awesome! Pulls as hard as it ever has. 2nd gear blows off every time now. Pulls harder than when I had a pump/race gas mix. I'm loving it! I'm gonna have to get back to the track soon and maybe even go back to the dyno just to see how much improvement ethanol has given me.

Well, now I know why my soldering is also crap lol.
Re: BackroadCR-V's High Mileage B18C1 + Boost Progress Build Thread
You could probably just hold the soldering iron on the bottom of the joint and after it heats up, the solder should flow in and create a proper joint, just take care not to overheat and burn up the resistor, if that is possible....
Re: BackroadCR-V's High Mileage B18C1 + Boost Progress Build Thread
The car has been running awesome. The e50 tune is dialed in and the car loves it. Runs soooo smoothly
i haven't driven the car a tone still on my 1st tank of ethanol. Still haven't trouble shot the timing spikes when the flex fuel sensor is turned on. I've been enjoying the car just as much on the e50 map. I guess even with flex fuel I had planned on only running 93oct on emergencies so I'm happy to just enjoy the car as is for now
the clutch has broken in nicely. I've been meaning to update on that. The pedal pressure has always been great, just a little more than stock, but the clutch grab was very on/off in the beginning. After I took it to the track that one time it began to soften up a touch and now it feels as if it's broken in nicely. It still grabs quickly but it's not bad. I've had much worse for sure. If I had to do it again I'd step down to a stg3 but I'm not unhappy with the stg4 at all.
I TURNED UP THE BOOST.
juuust a touch. Im up 1.5psi to 14psi now. With the e50 the car takes it like a champ. If I was still on 93oct pump gas I don't believe it would be safe; it think it would really start to push it. I think the higher octane in the ethanol is really what's keeping it happy at this point. On the dyno inwas about 350whp @ 12.5psi I would bet I'm about 370whp with e50 @ 14psi now. Car is running like a champ 👍🏼
Re: BackroadCR-V's High Mileage B18C1 + Boost Progress Build Thread
So where does the High Mileage B18c1 + Boost go from here? in thinking about my next steps im undecided about what I should do this winter.
When I began this build I really thought I'd only have around 300whp and drive it for awhile like that; see how it holds up. As with any build plans change. Truth is I enjoy working on and improving the car almost as much as getting to drive it. ALMOST lol. It's so fun to drive your own creation.
At this point the High Milage + Boost project has really exceeded my expectations. With the setup I have going I'm beginning to think this motor is going to last awhile at this power level with this tune. In a crazy way I'm starting to feel like the stock motor is holding me back from making anymore improvements. I'm not sure I want to wait as long as it could take for this thing to give up haha
i could go onto brakes, and interior or something but I'm really interested in building my own block (something I've not done yet). A block on the side that I can work on. Thing is soon as it's done I'm gonna be itching to put the new block in.
SO WHAT NOW?
id love to go dyno the car again. see what improvements ethanol plus more timing & boost has made. Should we see if we can make it a "High Milage b18 + 400whp" build thread? Lol See how long that lasts. Hell even if I have a built block on the side.... if the damn thing makes 400whp And keeps going I don't think I'd have the heart to pull it. It would deserve to stay in the car as long as it wanted to at that level!
What's funny is I only have a 15psi boost gauge because I thought it would be a long time before I got close to hitting 15psi lol.
At the same time though if it's making 370-ish now then 30hp isn't that much more for the fun-factor and why push it if it's going so well anyways. I just honseatly don't know what to do at this point. Don't know what I should do this winter. I just know I'm ready for the next step and not sure how to go about it. What do you think?
Re: BackroadCR-V's High Mileage B18C1 + Boost Progress Build Thread
IMO...move on to a different part of the car that could stand some attention (the car looks well cared for, I'm just speaking in general)...brakes, suspension, etc that would make the car as a whole more enjoyable. You will ALWAYS want more power (up until the point to where it scares you...then back it down a hair). Enjoy the power plant, focus on other parts to bring it all together without over complicating it. Just my $.02

I'll support this stance. This is assuming you still want the car to be both reliable and efficient as a daily driver. You're in a really good place right now, as Autoworks says I'd work a bit on the other areas of the car.
Building an engine would be a great experience for you, definitely, and seems like something you'd enjoy. I'd just wait a bit before jumping into it.

focusing on the rest of my car after I got the turbo kit complete.... That's actually been the plan from the start; 1st motor mods, then full brake upgrade, suspension uprgrade, lightweight sub 11lb wheels, then seats. I already scored a nice pair of oem black leather seats last month.
I spent nearly the 1st year replacing small things like bushings and stuff. There's really no maintenance to do that i have not already done. The last thing is replace stock brake lines and that goes with the brake upgrade. I just want to do the things mentioned above and build the bottom end (those are the big things anyways. Small bells and whistles always getting added along the way lol).
Only recently have I been second guessing if I should do built bottom end, or rest of car this year. honestly rest of car is much easier and less involve. More enjoyable work too lol
i guess I'll leave the motor as is then. I'm still interested in dyno'ing to the difference that e85 + 1.5psi has made. Looking forward to that.
Re: BackroadCR-V's High Mileage B18C1 + Boost Progress Build Thread
Maybe finish up the brake work and then source another b18 to build on the side. Take you time with building the spare engine and enjoy what you have for now. Then if your original engine starts showing signs of wear/failure or you really want to turn up the boost you can swap it in. I am of course more in favor of not destroying your original engine before swapping/building the spare engine lol...

A sleeved 84x89 with 10.5 -> 11:1 would be interesting if used in conjunction with the same turbo. A good set of turbo cams with the extra compression, on that tiny beast of a turbo with E85? THAT will be a monster on the street for sure.

...it may just run for as long as you want it to. I have a few local customers on stock motors (one of them being a stock D series, same turbo kit that has been boosted for YEARS) turboed that just take a licking and keep on ticking (no bearing pun intended). Clutches go, fuel pumps go, the motors just hang in there.

Re: BackroadCR-V's High Mileage B18C1 + Boost Progress Build Thread
Those days of blowing up the original engine as an excuse to start working on another engine are over. Especially because of the fact that so many people have used that ideology, that they had forgotten that these motors will run out of availability. Costs will simply keep rising to get good units.. So no, don't blow it up, that's just being stupid, for stupid's sake.
I'm in favor of working on the rest of the car itself including taking a second look at all of the bushings that you've already replaced, improving the chassis, work on ways of making what you already have efficient, and not worry about fuel comparisons do much.
Honestly, I'd start working on getting more seat time, and experience behind the wheel. Regardless of the type of racing that you plan to do, there's nothing more satisfying than taking the car to its full potential, knowing that you have the capable skills to make sure that it stays at that potential repeatedly.
start going to a few events. See if there are instructors that are willing to help you get better at driving the car itself. Understand your car better, not just worrying about making it faster.
there are so many fields, and people who concentrate so much on making the car faster, and never take the time to work on making themselves faster with the car that they already have.
no matter how much experience you have, you could always use more. There's no such thing as too much experience.
Re: BackroadCR-V's High Mileage B18C1 + Boost Progress Build Thread
i would not truly suggest to "blow it up". I think thats dumb myself, but the point of this thread was to see how a high mileage motor would handle boost. As we see it's not so much about the mileage as it is the condition. Truth is the motor has handled the mods VERY WELL, passing my best expectations. Although this is my 1st Honda to mod I didn't exactly know what to expect but I can tell you that I and others around me are all impressed.
The car now has 231609 miles. I've put over 2000 turbo miles on it. I've driven over 4x more turbo miles in a few months, than I did the whole 1st year N/A. I look the car over EVERY single time I drive it. I've changes the oil twice already (3 times if you count the fresh oil I started the turbo with). I check the plugs, I have a laptop in the car 90+% of the time recording datalogs. I'm very maticulas with it, BUT I also drive the socks off it. EVERY time I drive the car it sees WOT. I couldn't count how many highway pulls it has; i guarantee it's well over 100. All my WOT tuning is from 40-120mph in 4th gear (for max load). I'm constantly watching temps on the iPhone. There's no radio in the car, when Im driving I'm monitoring everything. I'm very in-sync & in- tune with the car.
I don't come on here to talk about my kill stories. I try to keep this thread on topic but the car is CERTAINLY a force to be recorded with. Bolt-on coyote mustangs, camaros, chargers, challengers, and whatever else can't pull me on the highway. It takes atleast a cam'd LS car to keep even with me. Cam/heads LS will pull on me, and boosted v8's will drag me, but other than that I'm dragging everyone else lol. 2750lb total weight (me included) with over 350+whp does VERY well against these cars that weight 1200-1700lbs more than me. The only disadvantage I have is at high Speed, v8 engine torque is much higher then mine and it starts to show at high speed. But then again my lower torque output is what's keeping this little motor alive so I'm fine with it.
I don't want to blow it up but as perfectly as it's running I believe it could probably handle more. if I truly thought it was on the edge of breaking, I'd back it off right this moment. Soon I'm gonna go dyno it again to see what my gains are from last time. Wether or not I decide to dyno at my current 14psi or turn it up one last notch... idk we'll have to see how I'm feeling the car out that day.
no matter what else I do with the car this winter, I'm gonna start building a block on the side. Building my own motor is something I've wanted to do for awhile now and I'm eager to start that as a new chapter in my build.

You're late a few years if your wanting to get into HP wars with the V8 crowd. Its a rule of diminishing returns these days. I would stick with < 400whp.

I concur with my colleague above, here, BackroadCR-V. And this is coming from LightninTeg who for years ran against these same guys you want to tackle in both VTEC and NON-VTEC B18 turbo systems, and has the video documentation to prove it.
Re: BackroadCR-V's High Mileage B18C1 + Boost Progress Build Thread
Oh I agree and I'm not trying too. I tried big HP with my DSM's that being a little more practical with the AWD advantage. I'm not interested in trying to squeeze out big hp with a FWD platform. My turbo kit was spec'd for around 400hp and that's where this car will stay for awhile. I'm not interested in slicks or any of that. I just wanna have a good time with a fun car
